Abstract
A moving object detecting apparatus is disclosed and includes a TV camera for generating an image signal in accordance with a scene including a moving object and a fixed object. A CPU takes the difference, between the image signals generated by the TV camera at different times to generate a subtracted image signal. CPU then sets a pointing window over the subtracted image corresponding to the subtracted image signal which includes an image corresponding to the moving object. A CPU analyzes signals generated by the TV camera, within the pointing window, and detects an image area corresponding to the moving object.
